Songwriter and vocalist Des McCab said: “In May, one of our bandmembers tweeted the song to Craig Ferguson. An hour later, he retweeted it, saying, ‘Another great band from Scotland’.

“He contacted us via direct message to ask us to play his show on October 3.

“Our visas were refused because we are unsigned and didn’t have enough credentials to pass immigration.

“Luckily we were contacted by producers who said they had another idea.”

Ferguson’s video featured A- list celebrities before ending up in the studio where he sang the song in front of a live audience. He had fronted the show for 10 years and is thought to be moving to an earlier slot. James Corden will fill his chair.

Des, a welding lecturer at Forth Valley College, said: “We’ve been going about two-and-a-half years and would never imagine that people like Mila Kunis, Quentin Tarantino, Metallica and Kevin Bacon would end up singing it.
